Dispensing device



P 1936- A. ASPLUND DISPENSING DEVICE Fi'led Sept. 1, 1933 51 ENE I INVENTOR HUGUSTHSPLUJYD,

Patented Sept. 8, 1936 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to improvements in dispensing devices and has particular reference to a dropper to be applied to containers, such as bottles.

The principal object of the invention is to provide a dispenser which may be moved from one bottle to another, in order to dispense the contents of the various bottles, a drop at a time.

A further object is to produce a device which is economical to manufacture.

A still further object is to produce a device which will seal the bottle contents after dispensing.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevation of a bottle equipped with my device as the same would appear in use,

Fig. 2 is a top plan view of Fig. 1,

Fig. 3 is an enlarged fragmentary detail view of a bottle shown partly in cross section, and showing my device with the parts thereof broken away,

Fig. 4 is an unassembled view partly in cross section of the valve mechanism of my device, and

Fig. 5 is a side elevation of the dispensing tube.

There are many commodities which are dispensed a single drop at a time, or a definite number of drops. These usually require the use of a medicine dropper in order to accomplish the proper measuring of the liquid. Applicant has, therefore, devised a cork which may be inserted in any ordinary bottle, which cork has a valve and dispensing tube positioned within the cork, and by pressing the valve a definite number of drops may be permitted to flow from the bottle.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a bottle having a neck 6. Within this neck is placed a cork l, which cork is bored so as to receive a shell 8 having a reduced portion 9, in which is slidably mounted a valve stem ll carrying the valve I2. The upper end of this stem is threaded so as to threadedly engage the positioned a spring l1. When assembled as shown in Fig. 3, the spring presses against the bottom of the shell 8 and against the underside of the head of the push button IS. A dispensing tube I8 is placed through the cork and has its lower end in alignment with the valve l2. 5 The result of this construction is that when pressure is removed from the push button "5 the spring I! will force the parts upwardly, causing the valve I2 to engage and seal the bottom of the dispensing tube [8, but when depressed as 10 shown in Figs. 1 and 3, the valve will bespaced a short distance from the end of the tube l8 and consequently a small amount of liquid will flow from the tube, and due to capillary action, only a drop will issue from the end of the tube, 15 at a time.

It will thus be seen that applicant has produced a device which may readily be placed in any bottle, and when actuated, will accomplish all the objects above set forth.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim. Having thus described my invention, I claim: In combination with the neck of a portable pocket container having a stopper positioned therein, of a discharged tube passing through the stopper for dispensing the liquid contents of the container drop by drop, means for control ling the passage of the liquid through said tube, said means comprising a casing embedded in the stopper, a valve having a stem threaded adjacent its upper end and provided with a valve head having a flat surface adapted to contact the lower end of said discharge tube, a push button equipped with a shank internally threaded adjacent its lower end adapted to receive therein the threaded stem of said valve, said pusher button being normally exposed to a minimum degree above the upper edge of the stopper and when depressed confined within the body of the stopper, and a spring surrounding the push button shank and normally tending to move said valve into contact with said tube for the purpose of sealing the end of said tube.
